Background information and definitions
Dredging disturbs the river or seabed, resulting in sediment plumes and increased turbidity, which may have negative impacts on marine and freshwater mammals (Todd et al. 2015). Methods may be used to reduce sediment disturbance during dredging. For example, fabric curtains or screens may be erected around the dredging site to retain suspended sediments (Oglivie et al. 2012).
